Hello... thank you for getting back with the image for my better understanding.
From your symptom analysis and correlating it with the images I feel that the possibility is contact dermatitis or atopic dermatitis or eczema.
This is a skin condition that makes your skin itchy and flaky. We do not know what causes it. This often happens in people who have allergies. It can also run in families.
The symptoms of eczema can include - Intense itching, regards, small bumps, skin that flakes off or forms scales.
Use unscented thick moisturizing creams and ointments to keep the skin from getting too dry. Also, try to avoid things like - Being too hot or sweating too much, being in very dry air, stress or worry, sudden temperature changes, harsh soaps or cleaning products, perfumes, wool or synthetic fabrics (like polyester).
Treatment modalities include moisturizing lotions, steroid creams, immunomodulatory drugs, antihistamines and phototherapy.
